Research shows that the benefits of higher-resolution audio recording (such as 24-bit/192 kHz) are “small and difficult to detect.” You can read more in our article about audio resolution. It’s important for you to be able to see and read the meters easily. Setting it too low can produce excessive noise and make a recording more difficult to mix.
If the level is too high, distortion (often called “clipping”) will result. These meters are critical for setting gain, or record level. Meter design: One of the biggest differences among USB interfaces is in the way their signal-level meters are configured.
A well-made interface, even if it’s made of plastic, should survive years of use.
